    LEM HAH1BVS/35 Open-Loop Hall Effect Current Sensor

     

    LEM HAH1BVS/35 Product Overview

    The HAH1BVS/35 is an open-loop Hall effect current transducer from LEM's HAH1BVS series, designed for electronic measurement of DC, AC, and pulsed currents in automotive high-power applications, with galvanic isolation between the primary and secondary circuits .

    This series is specifically optimized for automotive Battery Management Systems (BMS) and electric vehicle applications, featuring busbar mounting and offering various current measuring ranges in the same housing for flexible platform-based selection . The "35" suffix indicates a specific configuration version for this model, although the exact rated current for this suffix is not directly confirmed in the available search results.
